Proven is usually an adjective (e.g., a proven formula), and proved is usually the inflected form of the verb prove (e.g., I proved it; I have proved it). This is not a rule, though, and exceptions abound, especially in American English, where proven is often used as a participial inflection of the verb. For example, where a British writer is likely to write I have proved you wrong, an American writer might write I have proven you wrong.

Both forms are many centuries old. Proven appears in the 15th-century works of Chaucer, for instance. But proved has always been the prevalent inflection ever since prove emerged from its pre-Middle English roots, and only over the last century or so has proven gained significant ground. This doesn’t mean proven is wrong, though. It is a very well-established form, and only a few people from outside North America consider it questionable.
